Rincewind listened to the girl while keeping one eye on the patients. As interested as he was in the discussion of another world's magic, he had to live in this world and part of that was keeping his job as an orderly.
When all the nurses in the clinic started running to the front door, yelling about someone bleeding in the reception area, he jumped up with a start.
"Emergency! I have to check in on all the patients waiting in the clinic! There are probably enough nurses and orderlies running to help the emergency man, but someone has to look after everyone here."
He puffed up his chest.
"That's my job! You just wait here, I'll get you a doctor when they all get back. Stay here."
With that, he ran off to room 2 to check in on the little boy with the broken arm.
